# This Makefile should be complete enough for this project to be used as an
# erlang.mk dependency.
#
# Additional targets:
#
#  - tests-report:   Creates doc/eunit.html with the coverage and eunit output.
#  - gh-pages:       Generates docs and eunit reports and commits these in the
#                    gh-pages which Github publishes automatically when pushed.
#  - CHANGELOG.md:   Generates a changelog from the git commits and tags.
